Built for every weather, engineered for effortless access. The Big Max Aqua Sport 4 is a high-performance cart bag designed to handle all weather conditions, offering 100% waterproof protection thanks to the proven I-Dry system, an oversized cooling pocket, and wider pockets with easier access than ever before. More compact in profile yet more spacious in storage, and featuring a 14-way divider top and a strap-carry option, the AQUA Sport 4 is the perfect combination of durability, on-course comfort, and sophisticated design.
The AQUA Sport 4 is built on Big Max's industry-leading I-Dry waterproofing platform, which combines 100% waterproof materials, fully welded and sealed seams, and waterproof zip closures on every pocket. This triple-layer protection system has been engineered to withstand even the heaviest downpours, ensuring your clubs, clothing, and valuables stay completely dry from the first tee to the 18th green. Whether you're playing in light drizzle or sustained rain, you can trust the AQUA Sport 4 to deliver reliable protection round after round.
The 9.5-inch divider top is divided into 14 individual full-length compartments, making it easy to organise and access every club in your bag without tangles or delays. A dedicated putter well keeps your flat stick isolated and protected. The generous 9.5-inch top diameter provides ample space for today's oversized driver heads and hybrid covers, while the full-length dividers protect shafts and grips throughout the entire bag depth.
With 10 fully waterproof pockets in total, the AQUA Sport 4 offers an exceptional level of storage for a cart bag. Pockets are wider and positioned for easier access than previous generations, so you spend less time searching and more time playing. The XL cooling pocket has been enlarged to accommodate more drinks and snacks for longer rounds, while the dedicated valuables pocket provides a secure, waterproof environment for electronics and personal items. A separate rain jacket and battery pocket means your wet-weather gear is always at hand without taking up general storage space.
The AQUA Sport 4 comes with a built-in integrated rain hood that stores neatly in its own dedicated pocket, so it is always ready when you need it and never left behind in the car. A dual umbrella holder keeps two umbrellas securely in place, while the glove holder and towel ring ensure your accessories are always within easy reach. The Strap Fix system allows the bag to be carried comfortably on your shoulder when moving between the cart and the fairway, adding versatility to a bag that is primarily designed for cart use.
Despite its generous storage capacity, the AQUA Sport 4 has been engineered to keep weight to an absolute minimum. Starting from just 2.4 kg (without strap and rain hood, approximately 2.5 kg with accessories), it is one of the lightest fully waterproof cart bags in its class. The compact footprint fits neatly on all standard electric and push carts without taking up excessive space, and the top handle makes lifting and repositioning on the cart quick and effortless.
The AQUA Sport 4 is available in a bold and vibrant Off White, Steel Blue, and Fuchsia colourway that stands out on the course while maintaining a sophisticated, premium look. The colour-blocked design pairs perfectly with coordinating Big Max accessories and golf apparel. The clean, modern aesthetic reflects the bag's performance credentials — this is a bag that looks as good as it performs, regardless of the weather.
